About this map

The rugged topography of the Snoqualmie National Forest dominates this survey, where the Sultan River and Pilchuck River carve through high timberlands. Central to the landscape is the expansive Spada Lake, a reservoir that occupies the northern Sultan Basin, while the Wild Sky Wilderness borders the southeastern reaches. This area is characterized by dramatic elevation changes, evidenced by the presence of Wallace Falls and Olney Falls.

Evidence of historical resource extraction persists in the naming of Corona Mine Rd, which climbs toward Olney Pass. In the southwestern corner, the settlement of Startup represents the primary point of human habitation, situated near the confluence of the Wallace River and Bear Creek. The map documents a complex network of forest routes, including Sultan Basin Rd and the Wallace Lake Via Upper Falls Trl, providing access to isolated mountain waters like Cecelia Lake and Jay Lake.
